Answer:
Triangle C and D
Is your correct answer
Triangle A have 3 sides equal so it is equilateral triangle
Triangle B have 2 sides equal so it is isosceles triangle
Triangle C have no equal sides so it is scalene triangle
Triangle D have no equal sides so it is scalene triangle
Triangles C and D are scalene triangles.
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Triangle A has three sides each measuring 7 units.
Triangle B has two sides that are equal in length, and the base is longer than the two sides.
Triangle C has no sides of equal length.
Triangle D has sides of length seven, three, and six.
Now, We know that;
A scalene triangle have different sides.
Hence, Triangles C and D are scalene triangles.
Thus, We get;
Triangles C and D are scalene triangles.

The estimated regression equation was:_______
Answer:
ŷ = 1.85057X1 + 0.9688X2 + 84.77516
Step-by-step explanation:
Given the data:
Weekly Gross Revenue (Y) :
97
90
96
93

The regression equation obtained using a multiple regression calculator is :
ŷ = 1.85057X1 + 0.9688X2 + 84.77516
x1 and x2 are the predictor variables
y is the predicted variable (Weekly Gross Revenue).
Slope x1 = 1.85057
Slope x2 = 0.9688
Intercept = 84.77516

Share R600 amongst Tom, Paul and Anne in the ratio : 3:4:5 respectively.
Step-by-step explanation:
Total Shares = 3 + 4 + 5 = 12 shares
12 Shares = R600
(12÷12) Share = R(600÷12)
1 Share = R50
(1×3) Shares = R(50×3)
3 Shares = R150
4 Shares = R(50×4) = R200
5 Shares = R(50×5) = R250
Tom Gets R150.
Paul gets R200.
Anne gets R250.
HELP PLEASE A total of 29 bills amounts to $73.00. If there are only $1 and $5 bills, how many of each are there?
Answer:
18 $1 bills and 11 $5 bills.
Step-by-step explanation:
First, we use the guess-and-check method.
$5X29=$145
Then, $5-$1=$4.
$145-$73=$72
$72 divided by 4 is 18.
29-11=18
11x$5=$55
$1x18=$18
$55+18=73.
help please :((( this is the last math problem
Answer:
11.53 degrees.
Step-by-step explanation:
ok so we know the hyp and opp sides. this means that it is sin. according to SOHCAHTOA we do sin^-1(2/10). you should get 11.53
Answer:
11.5396°
Step-by-step explanation:
Please see the attached image
We can do sin(x)=2/10, which simplifies to sin(x)=1/5
To get x by itself do [tex]x=sin^{-1}[/tex](1/5) which ≈11.5396°

For whole numbers between 1 and 1001, inclusive, let m be the sum of odd numbers and n be the sum of even numbers. What is the value of m−n?
Answer:
m - n = 501
Step-by-step explanation:
Remark
The first thing you have to do is find the number of odd and even numbers. This is where you have to be careful because there is a danger of being out by one.
equation
l = a + (n - 1)*d
Solution even
l = 1000
a = 2
d = 2
1000 = 2 + (n - 1)*2
998/2 = (n - 1) * 2 / 2
499 = n - 1
n = 500
Solution odd
l = 1001
a = 1
d = 2
1001 = 1 + (n - 1)*2
1000 = (n - 1)*2
1000/2 = (n - 1)2/2
500 = n - 1
501 = n
Sum Even of even numbers from 1 to 1001
Givens
a = 2
n = 500
l = 1000
Equation
Sum = (a + l ) * n / 2
Solution
Sum = (2 + 1000)*500/2
Sum = 1002 * 250
Sum = 250500
Sum of Odd numbers from 1 to 1001
a = 1
l = 1001
n = 501
Equation
sum = (a + l)*n/2
sum = (1 + 1001) * 501
sum = (1002)*501 / 2
Sum = 251001
Answer
m - n = 251001 - 250500 = 501
Suppose that a random sample of eighteen recently sold houses in a certain city has a mean sales price of , with a standard deviation of . Under the assumption that house prices are normally distributed, find a confidence interval for the mean sales price of all houses in this community. Then find the lower limit and upper limit of the confidence interval.
This question is incomplete, the complete question is;
Suppose that a random sample of eighteen recently sold houses in a certain city has a mean sales price of $280,000, with a standard deviation of $10,000. Under the assumption that house prices are normally distributed, find a 95% confidence interval for the mean sales price of all houses in this community. Then find the lower limit and upper limit of the confidence interval.
Answer:
At 95%, confidence interval is ( 275026.7, 284973.3 )
Hence;
Lower limit = 275026.7
Upper limit = 284973.3
Step-by-step explanation:
Given that;
mean x = $280,000
standard deviation σ = $10,000
sample size n = 18
degree of freedom df = n - 1 = 18 - 1 = 17
∝ = 1 - 95% = 1 - 0.95 = 0.05
so
Critical t value = tinv( 0.05, 17 ) = 2.11
now, at 95% confidence interval for mean will be;
⇒ x ± [ Critical t value × ( σ/√n) ]
so we substitute
⇒ 280,000 ± [ 2.11 × ( 10000/√18) ]
⇒ 280,000 ± [ 2.11 × 2357.0226 ]
⇒ 280,000 ± 4973.3
⇒ 280000 - 4973.3, 280000 + 4973.3
At 95%, confidence interval is ( 275026.7, 284973.3 )
Hence;
Lower limit = 275026.7
Upper limit = 284973.3
( 7x + 1/2) + ( 7x - 7 and 1/2) Simplify
Answer:
The answer will be 7(2x - 1)
Step-by-step explanation:
1) Convert 7 and 1/2 to improper fraction. Use this rule: a b/c = ac + b/c
[tex]7x + \frac{1}{2} + 7x - \frac{7 \times 2 + 1}{2} [/tex]
2) Simplify 7 × 2 to 14 .
[tex]7x + \frac{1}{2} + 7x - \frac{14 + 1}{2} [/tex]
3) Simplify 14 + 1 to 15.
[tex]7x + \frac{1}{2} + 7x - \frac{15}{2} [/tex]
4) Collect like terms.
[tex](7x + 7x) + ( \frac{1}{2} - \frac{15}{2} )[/tex]
5) simplify.
[tex]14x - 7[/tex]
6) Factor out the common term 7.
[tex]7(2x - 1)[/tex]
Therefor, the answer is 7( 2x - 1 ).

18. Emma rents a car from a company that rents cars by the hour. She has to pay an initial fee of $75, and then they charge her $9 per hour. Write an equation for the total cost Cif Emma rents the car for h hours. If Emma has budgeted $250 for the rental cars, how many hours can she rent the car? Assume the car cannot be rented for part of an hour.
Step-by-step explanation:
Let h be the number of hours.
Total Cost = Fixed Costs + Variable Cost
= Initial Fee + Hourly Charge
= 75 + 9h
Given,
[tex]75 + 9h = 250 \\ 9h = 250 - 75 \\ 9h = 175 \\ h = 175 \div 9 \\ = 19 \frac{4}{9} hr[/tex]
Since the car cannot be rent part of an hour, the highest possible whole number is 19 hours.

Find the conjugate and product of
i3 + i7
Answer:
Complex conjugate: 2i Product: -2ifind the the ratio write the answer as a fraction and as a decimal rounded to four decimal places.
Answer:
7 degrees
Step-by-step explanation:
It has a right angle and it's a triangle so the angle is a complementary angle so the total for the angle is 90 degrees.
So then you add 39 + 44 and get 83
So, 90 - 83 +7
So your total is 7 degrees
